A rapid microanalytical method for the determination of chromium in urine utilizing flameless atomic absorptiontechniqe has been developed. By the use of a 2-channel type of atomic absorption spectrophotometer, urinary chromium concentration can be determined rapidly because the interference due to the smoke of other component which occure at the atomization of samples is corrected automatically. This method has been used for the determination of chromium in urine samples of individuals exposed to chromium and nonexposed. The chromium level, mean and standard deviation, found in urine of nonexposed group was 3.1±2.2 ppb, and that of exposed groups was 4.4±6.0 ppb inhabitants near the factory and 6.6±4.3 ppb for workers in the factory handling chromium.
